有没有办法传递一个列表来确定 django 表单中的字段？

Question

I have a list determined by an admin for which fields the user should be able to fill out. I have tried passing a subset of my fields into the fields variable in my forms.py but all the fields are still rendered in the template.

forms.py

class myForm(forms.ModelForm):

    myList = ['field1']

    field1 = forms.CharField(widget=forms.TextInput(attrs={'class': 'form-control'}))
    field2 = forms.CharField(widget=forms.TextInput(attrs={'class': 'form-control'}))

    class Meta:
        model = myModel
        fields = myList

Im just rendering my form with {{ form }} in my html. I dont get any errors but my app renders all the fields instead of just the ones in my list

Answer 1

try this code below:

class myModel(models.Model):  # Your Model
    field1 = models.CharField( .. )
    field2 = models.CharField( .. )


class myForm(forms.ModelForm):  # Your Form Model
    class Meta:
        model = myModel
        fields = ['field1']
        widgets = {
            'field1': forms.TextInput( attrs={'class': 'form-control'} )
        }
